What Is EGCG in Green Tea? Matcha's Top Compound

EGCG means epigallocatechin gallate (in full, (−)-epigallocatechin-3-gallate), the most abundant and most researched catechin in green tea. It is a plant polyphenol with the formula C₂₂H₁₈O₁₁, and it makes up 50-80% of the catechins in green tea leaves (Singh et al., 2011). A 2 g bowl of ceremonial matcha holds roughly 98 to 139 mg of it: the five ceremonial matchas tested by Meyer et al. averaged 56.57 mg per gram, about 113 mg per bowl (Meyer et al., 2023).

Updated September 28, 2026: added a breakdown of the four green tea catechins (EGCG, EGC, ECG, EC) with EFSA infusion data, a section on how much EGCG a tea bag actually delivers, and two new questions.

If you've spent any time researching green tea, you've seen those four letters everywhere. EGCG is the compound behind much of what makes this plant so interesting to scientists worldwide.

But there's a problem. The internet is filled with exaggerated claims about EGCG, from "137 times more antioxidants" headlines to promises that border on fantasy. We wanted to cut through the noise. As a tea company founded by a journalist who has visited Japanese tea farms firsthand and filmed a documentary about the craft, we believe the real science is compelling enough without the hype.

This guide breaks down what EGCG actually is, what peer-reviewed research says about its effects, how much you're really getting from different teas, and why the way you prepare your tea matters more than most people realize.

Key Takeaways

EGCG makes up 50-80% of green tea catechins and is the most studied polyphenol in tea research (Singh et al., PMC4082721). Per gram, matcha and loose-leaf green tea contain comparable EGCG levels. But matcha's real advantage is whole-leaf consumption: you drink all of the leaf's catechins instead of whatever the water pulls out, so the dose per bowl is predictable. Brew at 85C for 3-5 minutes, drink between meals, and skip supplements above 800 mg/day.

For a broader look at how these compounds support daily wellness, see our guide to the health benefits of matcha.

What Exactly Is EGCG, and Why Does It Matter?

EGCG (epigallocatechin gallate) is a type of catechin, which belongs to the flavonoid family of polyphenols. It accounts for 50-80% of the total catechins found in green tea leaves (Singh et al., 2011). That dominance is what makes green tea chemically distinct from black tea, oolong, or white tea, where oxidation converts EGCG into other compounds.

Think of catechins as a family. EGCG is the eldest sibling, the one that gets the most attention and does the most heavy lifting. The other members, EGC, ECG, and EC, contribute too, but EGCG has the largest molecular structure and the strongest antioxidant activity in lab studies.

That size is literal, and it is worth seeing. EGCG is a flavan-3-ol: a benzene ring (A) fused to an oxygen-containing ring (C), with a second aromatic ring (B) attached at carbon 2 and a galloyl ester at carbon 3. What separates the four catechins is simply which of those last two features they carry. EGC has the three-hydroxyl B-ring but no ester. ECG has the ester but only two hydroxyls on its B-ring. EC has neither. EGCG is the only one carrying both, and that is where its eight hydroxyl groups and its 458 g/mol come from.

Why does this matter for your cup of tea? Because EGCG is the compound behind most of the cardiovascular, metabolic, and neuroprotective research on green tea. When scientists study "green tea polyphenols," they're overwhelmingly studying EGCG.

EGCG vs ECG, EGC and EC: The Four Catechins in Your Cup

EGCG is one of four main catechins in green tea, and the other three are not the same molecule. They differ by two structural switches: whether the B-ring carries two hydroxyl groups or three (catechin versus gallocatechin), and whether a gallic acid ester sits at carbon 3 (gallate or not). Flip those two switches and you get the whole family: EC, EGC, ECG and EGCG.

This is more than a naming footnote. ECG and EGCG are the gallated pair, larger molecules that bind more strongly to proteins and lipids than the smaller EGC and EC. So when a supplement label or a study abstract says "catechins," it is describing the whole group, and the EGCG share of that group is not fixed.

The European Food Safety Authority tabulated all four across 100 brewed green tea samples (94 for EC) (EFSA, 2018). Per 100 g of brewed tea, standardized to 1 g of leaf per 100 mL:

Catechin	Mean (mg/100 g brewed)	Range across samples	Share of the four
EGCG (epigallocatechin gallate)	70.2	2.3 to 203	about 56%
EGC (epigallocatechin)	29.2	1.0 to 90.4	about 23%
ECG (epicatechin gallate)	17.9	2.8 to 140	about 14%
EC (epicatechin)	8.3	1.9 to 26.0	about 7%

Means and ranges from EFSA (2018), Table 2. Shares are our own arithmetic on those four means, which total 125.6 mg, and exclude the minor non-epi catechins.

Two things are worth sitting with. EGCG really is the dominant one, at roughly 56% of the four by weight, which lands a little below the 50-80% figure usually quoted for dry leaf. Infusion is selective, and the gallated catechins are not the easiest to pull out of a leaf. And every single row carries an enormous range. The ECG column alone spans 2.8 to 140 mg, a 50-fold spread between one cup of green tea and another.

Matcha shifts the ratios, not just the totals. In the Meyer measurements, ceremonial matcha held the highest EGCG of any grade tested at 56.57 mg/g and the lowest ECG, averaging about 6.8 mg/g across its five products (5.12 to 9.21), while one gunpowder green tea in the same study ran ECG up to 28.02 mg/g, four times higher (Meyer et al., 2023). EGC moves independently again: culinary matcha led that column at 28.58 mg/g, the one difference Meyer reported as statistically higher than both other grades, ahead of ceremonial at 22.52 and bagged at 20.22. Shading and the tencha process do not lift every compound in lockstep. They change the shape of the profile, which is part of why matcha and sencha taste so different from each other. We walk through that divergence in our comparison of matcha vs green tea.

How Much EGCG: Matcha vs Green Tea, per Gram and per Cup

A 2023 study by Meyer et al. measured EGCG across multiple tea types and found ceremonial matcha contains 56.57 mg/g, culinary matcha contains 50.53 mg/g, and bagged green tea ranges from 23.29 to 70.22 mg/g (PMC10665233). Per gram of dry leaf, the difference between matcha and quality loose-leaf green tea is modest, not the dramatic gap many websites claim.

Per cup, the answer depends on the tea, how long and how hot you brew it, and how much leaf you use. A bowl of matcha is predictable because you drink all of the powder: 2 g of ceremonial matcha at the Meyer average works out to about 113 mg of EGCG, and 2 g of culinary matcha to about 101 mg. Brewed green tea is far less predictable. USDA infusion data, tabulated by the European Food Safety Authority, average 70.2 mg of EGCG per 100 g of brewed tea (standardized to 1 g of leaf per 100 mL), but individual samples ranged from 2.3 to 203 mg, an 88-fold spread (EFSA, 2018). That figure is a normalization of composition data, not a measured extraction yield, so it should not be multiplied up into a cup dose. The useful way to read it is as a ceiling and a spread: 2.4 g of bagged leaf holds roughly 110 mg of EGCG in the first place (Meyer average), infusion recovers only part of that, and the 88-fold range tells you the part recovered swings enormously with temperature, time and leaf grade. A bowl of matcha sidesteps the whole question, because there is no extraction step to vary.

Serving	EGCG	Source
Ceremonial matcha, per gram	56.57 mg average (49.03-69.73 across 5 products)	Meyer 2023
Culinary matcha, per gram	50.53 mg average (36.70-62.15 across 5 products)	Meyer 2023
Bagged and gunpowder green tea, per gram of dry leaf	46.14 mg average (23.29-70.22)	Meyer 2023
Bowl of ceremonial matcha (2 g)	about 113 mg (98-139)	Calculated from Meyer 2023
Brewed green tea, per 100 g of infusion	70.2 mg average (2.3-203)	USDA data via EFSA 2018
Brewed green tea, per 100 g of tea	70.2 mg average (2.3-203 across 100 samples)	EFSA 2018, standardized to 1 g leaf / 100 mL
Typical daily EGCG from green tea, EU adults	90-300 mg a day (high consumers up to 866 mg)	EFSA 2018

The honest one-liner: a bowl of matcha gives you a known dose, a cup of green tea gives you a range. One more finding from the same Meyer study that we think matters: the bagged and gunpowder green teas had higher total phenolic content and antioxidant capacity than the matchas tested, and they were the cheapest products in the study. That's why we don't sell matcha on "more antioxidants." Its case is the whole leaf, the flavor, and a dose you can count.

This is where we need to talk honestly about the "137 times more antioxidants" claim. That number comes from a 2003 study by Weiss and Anderton that compared matcha to a single China Green Tips tea. It was one sample compared to one other sample. The same paper gives its own general figure in the same sentence: EGCG in matcha is "at least three times higher than the largest literature value for other green teas." The Meyer 2023 numbers are more modest. Ceremonial matcha at 56.57 mg/g sits inside the 23.29 to 70.22 mg/g range measured for bagged green tea, so per gram of dry leaf the honest picture is overlap, not a dramatic gap.

So is matcha actually special? Absolutely, but for a different reason.

The Whole-Leaf Advantage

When you steep loose-leaf green tea or a tea bag, how much of the catechins reach your cup depends on water temperature, steep time and how much leaf you use, and whatever stays in the leaves gets thrown away. With matcha, you whisk the stone-ground powder directly into water and drink the entire leaf. That means all of the powder's EGCG enters your cup.

Even if a high-quality sencha contains similar EGCG per gram, you're only consuming a fraction of it through steeping. With ceremonial matcha, you consume the whole leaf, every catechin, every amino acid, every trace mineral. That's the real matcha advantage, and it doesn't require exaggeration to be meaningful.

How Much EGCG Is in a Green Tea Bag?

A standard 2 g green tea bag holds roughly 92 mg of EGCG in its dry leaf, but the bag is not the cup. Meyer et al. measured bagged and gunpowder green teas at an average of 46.14 mg/g, ranging from 23.29 to 70.22 mg/g across the products tested (Meyer et al., 2023). Multiply by a typical 2 g bag and the leaf is carrying somewhere between 47 and 140 mg, with about 92 mg at the average.

What reaches your mug is a different number, and this is where most articles quietly stop. Infusion never empties the leaf. How much it pulls depends on water temperature, steep time and how finely the leaf is broken, which is exactly why EFSA's 100 brewed samples ranged from 2.3 to 203 mg of EGCG per 100 g of tea, an 88-fold spread (EFSA, 2018). Two people can brew the same style of tea and drink doses that differ by a factor of eighty.

So the honest answer to "how much EGCG is in a green tea bag" is: the leaf inside is reasonably predictable, and the cup you actually drink is not. A few things tilt it in your favor.

• Use hotter water and a longer steep than you would for flavor alone. Catechin extraction climbs with both, at some cost to sweetness.
• Squeeze or press the bag before removing it. A saturated bag holds back liquor that is just as concentrated as the rest of the cup.
• Take a second steep. The first infusion does not exhaust the leaf, and the second still carries meaningful catechin content.
• Check that the bag contains whole or large-cut leaf. Fannings and dust extract fast but are usually lower-grade leaf to begin with.

Bagged tea is not a poor choice, and the per-gram data above shows quality bagged leaf competing with culinary matcha. The catch is variability, not ceiling. If you want a cup where the dose is knowable, you have two routes: weigh your own loose leaf green tea so you control the leaf-to-water ratio, or drink the leaf itself as matcha and skip the extraction question entirely. We compare the options by compound in our guide to the healthiest green tea to drink.

What Are the Proven EGCG Green Tea Benefits?

The Ohsaki National Health Insurance Cohort Study followed 40,530 Japanese adults for seven years and found that women who drank five or more cups of green tea daily had a 31% lower risk of cardiovascular mortality (Kuriyama et al., JAMA, 2006). That large-scale, long-duration evidence is why cardiovascular researchers continue to study EGCG decades after its initial discovery.

Here's what the strongest evidence supports, organized by the quality of research behind each claim.

Cardiovascular Health

The JAMA cohort study remains one of the most cited pieces of evidence. Observational studies consistently link regular green tea consumption to improved blood lipid profiles and reduced oxidative stress markers. The mechanism appears to involve EGCG's interaction with endothelial cells, helping maintain blood vessel flexibility.

It's worth being clear: observational studies show association, not causation. People who drink five cups of green tea daily may also have other healthy habits. But the consistency of findings across multiple populations and study designs is what makes the cardiovascular evidence consistent.

Metabolic Support

A meta-analysis of eight randomized controlled trials found that 300 mg of EGCG per day increased energy expenditure by approximately 158 kJ/day (Kapoor et al., 2017). That's roughly equivalent to a 15-minute walk. Modest, but real, and it adds up over time when combined with other lifestyle factors.

EGCG appears to work by inhibiting catechol-O-methyltransferase (COMT), an enzyme that degrades norepinephrine. With COMT partially inhibited, norepinephrine stays active longer, which slightly increases warming effect. This isn't a dramatic fat-burning effect, but it's a measurable one.

Cognitive Function

The PENSA trial added an EGCG-rich green tea extract (5-6 mg per kg of body weight) to a 12-month lifestyle program for 129 adults aged 60-80 who carry the APOE-ε4 gene variant and report memory concerns. It missed its primary goal: on the main cognitive score, the EGCG group did not differ significantly from placebo. The EGCG group was, however, 2.6 times more likely to show a reliable cognitive improvement, and the authors call it a proof-of-concept that needs larger trials (Forcano et al., 2025). Note the dose, too: that's an extract, far above what any cup of tea delivers.

What makes the cognitive research interesting is that EGCG can cross the blood-brain barrier, which many dietary compounds cannot. It appears to interact with amyloid protein aggregation pathways in cell studies. But we want to be honest: the leap from cell studies to human outcomes is enormous. More trials are needed before anyone should drink matcha expecting cognitive protection.

Antioxidant Activity

Green tea, specifically matcha, shows impressive antioxidant capacity in lab measurements. One study found matcha beverages contained flavonoids at 1,968.8 mg/L and polyphenols at 1,765.1 mg/L (Jakubczyk et al. (2020)).

A caveat: in vitro antioxidant measurements don't translate directly to in vivo effects. Your body has its own antioxidant systems, and dietary antioxidants work within that complex framework rather than simply adding on top. The research is compelling, but we should be honest about the gap between lab measurements and real-world health outcomes.

How Does Your Body Actually Absorb EGCG?

Oral bioavailability of EGCG is remarkably low, just 0.1-0.3% of what you consume reaches your bloodstream in active form (Andreu-Fernández et al., 2020). EGCG plasma concentrations peak between 1-4 hours after ingestion, with a half-life of approximately 3.9 hours (PMC9820274). Understanding this pharmacokinetic profile changes how you should think about tea consumption.

Why is bioavailability so low? EGCG is unstable in the alkaline environment of the intestine, it's rapidly metabolized by the liver, and much of it gets broken down by gut bacteria before absorption. This is actually why traditional tea-drinking cultures intuitively got it right: they drink multiple small cups throughout the day rather than one large dose.

What Helps EGCG Absorption?

Timing appears to matter most. In a 10-person study of an EGCG extract, taking it with breakfast instead of fasting cut absorption by about 30% in the women and by more than half in the men (Andreu-Fernández et al., 2020).

Practical implication: drink your matcha or green tea between meals if catechin uptake is what you're after.

What Reduces EGCG Absorption?

Dairy proteins bind to EGCG and may reduce bioavailability, though the research here is mixed. Catechins can also reduce iron absorption, so space tea away from iron supplements. Large meals consumed alongside tea can cut EGCG uptake dramatically. And EGCG degrades quickly in alkaline conditions, which means baking soda and antacids are not great companions for your tea.

For the record, the low bioavailability number sounds alarming, but it doesn't mean green tea is ineffective. The epidemiological evidence from populations drinking green tea daily for years is clear and positive. Bioavailability may be low on a per-cup basis, but consistent daily consumption over time is where the benefits appear to accumulate.

Does Brewing Method Affect EGCG Levels?

Water temperature is the single biggest variable. Research shows that brewing green tea at 85C (185F) for 3-5 minutes maximizes EGCG extraction (PMC4573099). Hotter is not automatically better, and cooler water extracts more slowly.

For matcha, the equation is simpler. Since you're consuming the entire leaf, extraction efficiency is less relevant. But water temperature still matters for taste: 70-80C produces a smoother, sweeter bowl. Boiling water makes matcha bitter by extracting excess tannins alongside the catechins.

Practical Brewing Tips for Maximum EGCG

For loose-leaf sencha, heat water to 80-85C, steep for 2-3 minutes on the first infusion, and don't discard the leaves after one steep. Second and third infusions extract additional catechins.

For ceremonial matcha, sift 1-2 grams of powder into your bowl, add 70-80ml of 75-80C water, and whisk vigorously with a chasen (bamboo whisk) until frothy. You're getting the full catechin payload regardless of steep time, because there are no leaves to discard.

For brewing tips that maximize EGCG extraction, see our matcha temperature guide.

Is EGCG Safe? What About High-Dose Supplements?

The European Food Safety Authority (EFSA) reviewed the evidence and concluded that EGCG supplements delivering 800+ mg/day have been linked to elevated liver enzymes in some individuals (PMC7009618). The same panel could not identify an EGCG dose from extracts that it would call safe. Brewed tea is a different story: EFSA considered catechins from traditionally prepared green tea generally safe at the amounts Europeans already drink, and in one study it reviewed, three cups a day delivering 704 mg of EGCG for 14 weeks produced no rise in liver enzymes. A separate systematic review of 159 human intervention studies proposed 704 mg a day as an observed safe level for tea in beverage form (Hu et al., 2018). There is a meaningful safety distinction between drinking tea and swallowing concentrated extract pills.

To put these numbers in perspective: a typical bowl of matcha (2g powder) contains roughly 113 mg of EGCG based on the Meyer 2023 data. A cup of brewed green tea is harder to pin down: USDA infusion data average about 70 mg per 100 g of brewed tea, with an 88-fold spread between samples (EFSA, 2018). You would need to drink 7-8 bowls of matcha daily to approach the 800 mg threshold, and even then, the beverage form appears to be processed differently by the liver than concentrated supplements.

Why Supplements Carry Different Risks

Capsules deliver a bolus dose of EGCG that hits the liver all at once. Tea delivers EGCG gradually, alongside other compounds (L-theanine, other catechins, minerals) that may modulate its effects. The food matrix matters. This is why food scientists generally recommend getting EGCG from tea rather than pills, and why EFSA drew the distinction they did.

If you're taking green tea extract supplements, discuss the dosage with a healthcare provider. For tea drinkers, even enthusiastic ones consuming 4-5 cups per day, the safety profile is excellent based on both the clinical evidence and centuries of traditional use in Japan.

How Does EGCG in Matcha Compare to Other Polyphenol Sources?

Matcha stands out among polyphenol-rich foods for its concentration and delivery. Jakubczyk et al. (2020) measured matcha beverages at 1,968.8 mg/L for flavonoids and 1,765.1 mg/L for total polyphenols (PMC7231151).

But comparing polyphenol sources is tricky. Different polyphenols do different things. The resveratrol in red wine isn't interchangeable with the EGCG in green tea. Quercetin in onions works through different pathways than catechins. What makes EGCG interesting isn't that it "beats" other polyphenols, it's that EGCG is the most studied polyphenol in human research, giving us better data on what it actually does.

A practical approach: don't chase a single compound. Eat a variety of colorful, polyphenol-rich foods and include green tea as one pillar of that approach. The epidemiological evidence supporting green tea comes from populations that drink it daily as part of a broader dietary pattern, not from people hyper-optimizing a single molecule.

Try it yourself with our organic ceremonial matcha, sourced directly from Japanese farms.

What Does the EGCG Timeline Look Like in Your Body?

EGCG reaches peak plasma concentration within 1-4 hours after consumption, then declines with a half-life of approximately 3.9 hours (PMC9820274). This pharmacokinetic profile helps explain why traditional Japanese tea culture involves multiple servings throughout the day rather than a single large dose. Spreading your intake maintains steadier blood levels of the compound.

Here's what this means practically. If you drink matcha at 8 AM, about half the EGCG is cleared from your blood by noon. A second cup at lunch refreshes those levels. Three moderate servings spread across the day likely produce more consistent EGCG exposure than one large morning dose, and the rhythm also suits the caffeine, which arrives alongside L-theanine rather than on its own.

The full pharmacokinetics, including what the measured human numbers are, why matcha behaves differently from a brewed cup, and whether EGCG accumulates with daily drinking, are covered in our dedicated breakdown of the EGCG half-life.

Where that suggestion comes from: spreading three servings across the day is our own inference from the 3.9-hour half-life and the tea-drinking rhythm we saw on Japanese farm visits. No trial has tested it as a protocol.

Because EGCG's effect on fat oxidation is the mechanism most people are chasing, it pairs naturally with our practical guide to the best matcha for weight loss, which covers grade, dosage, and daily ritual.

Frequently Asked Questions About EGCG in Green Tea

What is the difference between EGCG and ECG?

Both are gallated catechins, meaning both carry a gallic acid ester at carbon 3. The difference is the B-ring: EGCG has three hydroxyl groups on it (the "gallo" in epigallocatechin), ECG has two. In practice EGCG is far more abundant. Across EFSA's 100 brewed green tea samples, EGCG averaged 70.2 mg per 100 g against 17.9 mg for ECG, roughly four times as much (EFSA, 2018). EGCG is also the one nearly all of the clinical research has studied, so claims made about "green tea catechins" usually rest on EGCG data.

Do green tea bags contain EGCG?

Yes, and at a per-gram level competitive with matcha. Bagged and gunpowder green teas averaged 46.14 mg/g of EGCG in the Meyer analysis, against 50.53 mg/g for culinary matcha (Meyer et al., 2023). A typical 2 g bag therefore holds around 92 mg in the leaf. The uncertainty is not whether the EGCG is there, it is how much of it your particular brew extracts, which is why brewed cups vary so much more than bowls of matcha.

What does EGCG stand for?

EGCG stands for epigallocatechin gallate, more precisely (−)-epigallocatechin-3-gallate. "Epi" refers to its 2,3-cis geometry, "gallocatechin" to the catechin core with a three-hydroxyl B-ring, and "gallate" to the gallic acid ester at carbon 3. It is the main catechin in green tea and matcha, making up 50-80% of green tea catechins (Singh et al., 2011).

How much EGCG is in one cup of matcha?

A standard bowl of matcha uses about 2 grams of powder. Based on Meyer et al. (2023) data showing ceremonial matcha contains 56.57 mg/g (PMC10665233), one serving delivers roughly 113 mg of EGCG. Because you consume the whole leaf, all of that EGCG enters your cup, unlike steeped tea, where some of it stays behind in the discarded leaves. A cup of brewed green tea can hold anywhere from a few milligrams to well over 100 mg, depending on the tea, how long and how hot you brew it, and how much leaf you use (EFSA, 2018).

Is EGCG destroyed by boiling water?

Boiling water doesn't destroy EGCG. Brewing research indicates that 85C for 3-5 minutes optimizes extraction without excessive degradation (PMC4573099). For matcha, use even cooler water (75-80C) since you're consuming the whole leaf and don't need high temperatures for extraction. The lower temperature also produces a smoother, less bitter taste.

Can you take too much EGCG?

From tea beverages, it's difficult to overconsume. EFSA considers traditionally brewed green tea generally safe at typical intakes, and a study it reviewed saw no liver-enzyme rise at 704 mg a day from three cups of tea (PMC7009618). The concern is concentrated supplements at 800 mg a day or more, which raised liver enzymes in clinical trials. Stick to tea rather than extract capsules, and a few bowls of matcha a day (about 113 mg each) stays well below that.

Does matcha really have 137 times more EGCG than green tea?

No. That widely repeated claim comes from a single 2003 study (Weiss and Anderton) that compared matcha to one commercial green tea (China Green Tips), and it measured EGCG rather than total antioxidants. The same paper puts matcha at "at least three times higher than the largest literature value for other green teas", and the broader Meyer et al. (2023) testing shows the per-gram ranges overlap. Matcha's genuine advantage is whole-leaf consumption, meaning you drink all of the leaf's catechins rather than only what the water extracts.

Should I drink green tea on an empty stomach for more EGCG?

A small study found that taking EGCG with breakfast cut absorption by roughly a third to more than half compared with fasting (PMC7278615). Drinking tea between meals, rather than with food, likely improves catechin uptake. However, some people experience stomach discomfort from green tea on a completely empty stomach. A light approach: drink your tea 30-60 minutes before or after meals rather than alongside them.

The Bottom Line on EGCG Green Tea Benefits

EGCG is the most abundant and most studied catechin in green tea, with genuine scientific evidence supporting cardiovascular, metabolic, and antioxidant benefits. The research is strongest for consistent, long-term consumption of green tea as a beverage rather than short-term supplementation.

Matcha's real advantage isn't an inflated "137 times more" figure. It's that you consume the entire leaf, getting all of the leaf's EGCG in every serving. Combined with proper water temperature, between-meal timing, and daily consistency, matcha is one of the most efficient ways to incorporate EGCG into your life.

We source our matcha directly from organic farms in Japan because origin and processing quality directly affect catechin content. If you're looking to start or upgrade your green tea practice, our USDA Organic Ceremonial Matcha delivers a clean, vibrant catechin profile in every bowl. And for those who prefer the ritual of steeping, our organic Japanese sencha is a beautiful daily companion.

The science of EGCG is still unfolding. What we know today is compelling. What we'll learn in the next decade may be transformative. In the meantime, the simplest advice is also the oldest: drink good tea, drink it often, and enjoy the practice of it.
